Cross-check
A cross-check is an independent or materially different way of testing the same calculation, claim or result.
Agreement between two methods can reduce the chance that a conclusion is caused by a bug, unstable approximation or representation-specific artefact, although it is not automatically the same as independent external reproduction.
